Title: Residual chlorine concentration measuring equipment
Inventor: NODA NAOHIRO
IPC: G01N27/416
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To obtain a residual chlorine concentration measuring equipment of a non-regent method which does not need maintenance and is excellent in measurement accuracy. SOLUTION: This equipment consists of a residual chlorine concentration meter 1, a pH measuring means 3, an electric conductivity measuring means 4 and a signal processing part 3. On the basis of a correction curve concerning the pH dependency and the electric conductivity dependency of apparent residual chlorine concentration which is normalized to the true value of residual chlorine concentration, the signal processing part 3 determines correction coefficients to measured pH and electric conductivity of sample water, and calculates true residual chlorine concentration by dividing the measured apparent residual chlorine concentration of the sample water by the correction coefficients.

Title: Optical fiber cable
Inventor: HAYASHIZU YOSHITOSHI
IPC: G02B6/00
Filed: 1991-05-24
Abstract: PURPOSE:To improve the conveyance performance of the optical fiber cable and to prevent the transmission loss from increasing by varying the foaming rate of foamed coating layers from inside to outside. CONSTITUTION:The optical fiber cable which has the foamed coating layers 16, 26, and 36 of plastic outside is carried and laid in a tubular path under the pressure of gas, and the foamed coating layers 16, 26, and 36 are varied in foaming rate from inside to outside. When the foaming rates of the outside parts of the foamed coating layers 16, 26, and 36 are thus increased, the surfaces become uneven to reduce the area of contacting with the internal wall of the tubular path for pneumatic conveyance and decrease the contact resistance and contact friction, and the air resistance, on the other hand, increases, so the conveyance of the optical fiber cable is facilitated. When the inside foaming rates are decreased, the internal surfaces of the foamed coating layers 16, 26, and 36 become smooth and an external force is hardly applied to the inside coated optical fiber 4, so microbending is reduced and the transmission loss is prevented from increasing.

IPC: G01S17/14
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To constitute a distance-measuring apparatus whose resolution is high by using a clock signal generation part whose clock frequency is low and a counter whose operating frequency is low. SOLUTION: A plurality of counters C1 to C10 start a counting operation simultaneously by a start signal which is output in synchronization with the light-emitting timing of pulsed light from a light-emitting device. On the other hand, the respective counters C1 to C10 stop the counting operation when a stop signal is input at a timing which is delayed sequentially by ϕ (=T/10, where T represents the cycle of a clock signal) from a light-receiving timing at a photodetector 13. A mean computing part 25 finds the mean value of counted values by the respective counters C1 to C10, the counted values are multiplied by cT/2 [where (c) represents the speed of light], and a distance up to an object 9 is found.

Title: Magnetic disk device
Inventor: ITO KATSU
IPC: G11B25/04
Filed: 1992-05-19
Abstract: PURPOSE:To facilitate the thinning and the weight reduction of the device by arranging the center shaft of rotation of an arm and the center shaft of rotation of a spindle motor on one side of an intersection and on one diagonal line. CONSTITUTION:The center shaft of rotation 110 of the spindle motor 106 and the center shaft of rotation 116 of the arm 114 are arranged on one side of the intersection 144 to a diagonal line b142 on the diagonal line a140 of a rectangle base 104. Thus, when external force is applied on end points 150 and 154, the base 104 is easy to flex on the diagonal b142 as a center, but the parallel of the shafts 116 and 108 is kept. Consequently, even when a careless external force is applied at the time of being carried or the like, the effection of enternal deformation is reduced then the device is thinned and reduced the weight with high reliability. Also, when the attaching surface of the motor 106 to the base 104 or the attaching surface of an actuator to the base 104 are wide, the whole base is reinforced by arranging and fixing to the intersection part 144.

Title: Printing pitch measuring device for packaging synthetic resin film
Inventor: HONMA SHUNSUKE
IPC: G01B21/06
Filed: 1987-06-17
Abstract: PURPOSE:To automatically adjust the tensile force of a synthetic resin film in the transfer line to an optimum value, by detecting a printed mark on the moving synthetic resin film and the moving speed of the film. CONSTITUTION:A mask detector 1 generates a detection signal P1 in pulses every time a mark M passes the mark detector 1 in accordance with the movement of a synthetic resin film F. On the other hand, a speed detector 2 generates a detection signal P2 corresponding to the moving speed of the film F. These detection signals P1 and P2 are amplified by an amplifier 3 to be inputted to an operation unit 4 which in turn obtains the continuous average or moving average of the pitch between the adjacent two marks M on the basis of the detection signals P1 and P2. The operation unit 4 further compensates for the inspected value by the use of a predetermined operation formula, in consideration of the slippage between the speed detector 2 and the surface of the resinous film F. Then, the obtained continuous average or moving average is indicated on a display 5, printed out to a printer 6 or stored in a memory 7 as the confirmation data of the extension of the film F. Thus, the tensile force of the film F can be automatically adjusted to an optimum value.
